Holden’s current VF Commodore SS is only offered with the 360 horsepower 6.0-liter V8, which is outclassed by the all-new Ford XR8’s 450 horsepower supercharged 5.0-litre V8. With the Commodore’s demise imminent beyond the 2016 model year, Holden must act quick to make sure its beloved rear-wheel drive sedan goes out with a bang.
According to Australia’s Motoring.au, General Motors plans to ship its 6.2-liter LS3 V8 down under for use in the 2016 model year Commodore SS. Variations of the 6.2-liter LS3 are already installed in Gen-F HSV Clubsport and Chevrolet SS models at Holden’s Elizabeth plant, so strapping the engine under the hood of the lesser Commodore models should be an easy task.
When the Commodore SS receives LS3 power, output would likely rise to around 425 horsepower, the same as the Chevrolet SS. However Motoring points out there are two more powerful versions of the naturally-aspirated LS3 in Oz. The SV LS3, available in the HSV R8 Commodore, has a high flow exhaust and other upgrades to produce 455 horsepower, while the previous-gen R8 LS3 available in current HSV ClubSport and Maloo models produces 435 horsepower.
Using the more powerful LS3 engines would put output of the 2016 Commodore SS closer to that of the supercharged XR8, however it would also force HSV to revamp their product lineup to offer more performance than standard V8 Holdens. For that reason, we see Holden opting for the standard Chevrolet-sourced LS3 in this scenario.
